Density-Functional Theory (DFT) offers a simplification to electronic structure problems by using the electron density instead of the wave-function. Unlike the wave-function which is a function of 3N variables (excluding ...

Simulation engineering employs the use of simulation models, simulation environments, and simulation execution platforms in providing applicable Modeling and Simulation (M&S) solutions for studying complex systems. Discrete ...

Social networking systems have found their way into all sectors of life. With the advent of social coding platform like GitHub, networks of developers can be inferred based on the projects they participated in. When a new ...

A gas condensate reservoir is a type of gas reservoir that exists when the reservoir temperature is between the critical temperature and the cricondentherm. Compositional simulators are used to simulate these types of ...

In this thesis we explored the production of highly coherent and energetic extreme ultra violet(XUV) radiation through the process of high harmonic generation(HHG). HHG is a process by which a ultrashort laser pulse interact ...

Uncertainty analysis of flow performance predictions involves identifying significant reservoir parameters impacting the flow response. Uncertainty analysis often requires conducting large number of reservoir simulation ...

Low-grade iron ore sample was collected from Gangra mines in Nimba Liberia. The ore was subjected to XRD and XRF analysis and was found to contain 63.1% Fe2O3, 25.4% SiO2, 9.1% Al2O3, and 2.4% LOI. 561.5 g . 1684.5g raw ...

Nigeria ranks among the top ten petroleum producers in the world with over eighty petroleum Investors in its upstream sector. This creates an enormous challenge for the upstream institutions’ managers especially in the ...

The use of Magnesium oxide (MgO) cement as a full replacement and viable alternative for Ordinary Portland Cement was studied. Rice husk, an agricultural waste, was calcined and synthesised to be used as a source of silica ...

There is insufficient literature for annular flow and applications of Machine Learning in the petroleum industry; thus, this thesis is centred on annular flow prediction. Liquid holdup and flow behaviour during annular ...

This study presents the results of a combined theoretical, experimental and statistical study of the mechanical performance of stabilized lateritic soil for sustainable construction applications. The lateritic soil was ...

The study of variational inequalities frequently deals with a mapping F from a vector 0 space X or a convex subset of X into its dual X . Let H be a real Hilbert space and a(u, v) be a real bilinear form on H. Assume that ...

One of the important petrophysical parameter in reservoir description is the permeability distribution in a given reservoir. It is well known that most reservoir are heterogeneous in nature and homogeneous ones been the ...

Waterflooding is a secondary recovery process in which water compatible with the reservoir of interest is injected into the reservoir to displace residual oil. The goal of waterflood management is to maximize oil recovery ...

The work of Osilike and Isiogugu, Nonlinear Analysis, 74 (2011), 1814-1822 on weak and strong convergence theorems for a new class of k-strictly pseudononspreading mappings in real Hilbert spaces is reviewed. We studied ...

The practical application of various production parameters and relations to predict the well performance analysis of a solution gas drive reservoir is the primary objective of this study. These parameters include: IPR ...

We consider classical Finite Difference Scheme for a system of singularly perturbed convection-diffusion equations coupled in their reactive terms, we prove that the classical SFD scheme is not a robust technique for solving ...
